How long the journey will take bus from Dunhuang to Turpan? Is there any sleeper bus for this route?

I heard that there is only one departure each day. It departs at 8:00, and the sleeper costs around CNY 120. The trip may take 8 to 10 hours.

You may take a bus to Liuyuan from DH Bus Station. The buses are available from 09:00 to 19:50, and the trip takes about 1.5 hours. The fare is around CNY 36. Upon arrival, take a bullet train to Turpan (about 3.5 hours). A second class seat costs CNY 195.5; a first class seat costs CNY 234.5.

The second mode of transport is recommended to you!

Thanks a lot Dave, really appreciate it!
